Introduction

In this training, you will learn how to construct an Animation class and add animations to a label.

Steps:

• PropertyAnimator Class

Prerequisites

You have prepared the Host PC with all the development software tools and Ensemble Graphics Toolkit source code as explained in:

• Ensemble Graphics Toolkit – Preparing the Host PC and Target

You have installed and prepared the Eclipse IDE for C/C++ Developers as explained in:

• Ensemble Graphics Toolkit -- First Application using Eclipse IDE

You have performed the exercises in:

• Ensemble Graphics Toolkit: Timers

PropertyAnimator Class

In this section, you will modify the timer.cpp source code that you entered in the Ensemble Graphics Toolkit: Timers training to construct an Animation class and add an animation to the “Ensemble Graphics Toolkit” Label.

Observe the WVGA Display on the target:

The timer.cpp executable is running remotely on the target.

Observe the Label “Ensemble Graphics Toolkit” at the top of the WVGA Display move (animate) along the “easing_bounce” curve for a duration of five seconds.
